To who-tor may noncrrn:

Be Elm-awn lhat i, BUDOLF Guam, a subjoct of the Emperor of Austria-Hungary, rosiding at Vienna, Austriwliungary, have invented certain new and useful Improvements in Sebtionnl Girllers and Columns Formed of Con-35st? S eugthenscl with Iron, of which the following is a speoificzztion.

This iuv'sv n relates to sectional girdurs oil 0; concrete strongh ood with iron Jo ners, Lllt :seotions of which an readily put together and can be easily taken to pieces, and which sections may he manu 'zzcturod in bull: and only pin. logolher at the place (ACNE they used, the mill in; into girders or columns luring "-ll'noird by resting up the iron inlays. bliu'h that the concrete body at those places whore the ends of the iron inlays are situated 21H formed with rocesses during the moldidg process, so that lhe ends of these iron inlays :zro thus ox'pl d and can be connected togollivr by scrowed on'zo them or in nnjntlwr suitable manner adapted to bring: the girders or the fiolumn-sbutions into close contact.

Figures 1 and of the accompanying illustrative dmwin zd show in sl l-3 View and 0nd View, respeatively, our construction of girder according to this invention. Fig. 3 shows tho parts thereof disconnected one from tho other. Figs. 4: and 5 show in el'evlition and section, respectively, n column :uoording to this inveniion; and Figs. 6 and 7 show in p -rspeotive 5% portion or section of such n girdor .ml ii poruion or SiCl-lUIl of auch'o cohnnn, rv s p-actively.
